Re: Interest for MiniHID Li-Ion rechargeable solut

Ahhh, nice to see the list is being managed responsibly by each person who expressed interest and you are nicely looking out for each other /ubbthreads/images/graemlins/smile.gif I will lock-in the quantity from the list in a couple of days so I can plan what parts are needed to fill the rest.

I had too many uncertain expressions of interest and quantity during the initial phases as I progressed through the initial concept to design of working model to be certain. You can obviously look after yourselves with the list so keep it up.

Progress...

I have all parts including power supply boards to begin the first batch with the only exceptions being the fibreglass laminate for the ends of the holder and the boost regulators. Modamag has worked double time getting the IC's in real quick time and now he's working double time again to get the rest covered /ubbthreads/images/graemlins/smile.gif. May take a couple of weeks though, so please be patient - it's out of our hands and up to the suppliers. The IC's for the first batch should be here next week and I am expecting the PCB laminate routed just right to be here next week also.

I thought the LT IC solution would be a lot longer coming but it seems it's closer than thought /ubbthreads/images/graemlins/grin.gif.


BTW, a thought for you to consider....

There is a 3A fuse to the circuit. This is because I personally am concerned about any electronic item being left connected potentially unattended to a high energy source like Li-Ions . None of the converters I know of out there including the very popular badboys, madmax and many others do this without a fuse and there have been no problems. I'm just safety conscious.

This needs to be considered as if you intend to connect this to a high powered incan or short the output as you tinker with it (if you do) the fuse may blow due to low cold resistance of the incan filament or a short. If you intent to tinker, best you add the option - no fuse. If you use it for MiniHID only, I recommend leaving the standard option of having the fuse left there.

Be warned though; no fuse means that if you short the output or massively overload this you may damage the diode or inductor that is connected between input and output of boost converters. Not just this one, but any I have seen offered here on CPF.

If you are MiniHID only, go the standard fused circuit. If you are a tinkerer or want to experiment with 10W+ incans then specify no fuse, but it's your risk and I accept no responsibility for the consequences.

Thanks for doing this Chris. I'm guessing if 1768's will work it should be OK with 1767's?

Can anybody recommend a good source for bare 1765's?

[/ QUOTE ]

Bob,

The only hassles to-date are length of cell considerations with the holders. The holder I did for myself was not capable of > 1765's length. Seems many wanted Pila168S (17680 size). I am working hard to see if I can make some for others to suit a 17680/Pila168 sized battery so they can share in what I already have, but better. I have not done a 1768 capable pack yet, but looks like next week maybe the moment of truth as the parts come in so I can try.

If all is OK then 1765/67 or 68 will be OK. Just have to wait and see though. Best to hold off looking for 1765's for a week or so. The 1767's would fit best - not too tight, not too loose. A Pila 168S/17680 will be as tight as the standard holder is for 2 X 123's in series - not much room.

Fingers crossed guy's,

Chris

Re: Interest for MiniHID Li-Ion rechargeable solut

Bunrt Retinas,

I was talking with Ted Bear and he said that he knew for sure that the ballast we are using can actually handle 16V. He told me it would be fine to use 4 R123's (4.2V kind) in it.

If thats the case, perhaps we can step up the voltage with your regulators if you want to take a chance.

Someone needs to experiment with this (4xR123). I trust him because he is very knowledgeable but I'm still scared to try.

Who wants to do it and measure the lux with 4xR123?Batterystation R123's charge to 4.18V.

 

[gregw]

Re: Interest for MiniHID Li-Ion rechargeable solut

Hmmmm... I think Ted Bear may be mistaken. The ballast from the latest Ufokillerz MiniHID Groupbuy uses the WA B10N008 Ballast. According to the Specification Document (B10N008 at 2nd page top), this ballast is rated at an input voltage for 10W at 10.2V, a Max Safe continuous voltage of 11V, and an Absolute Max Instantaneous voltage of 11.8V.

Using 4xR123 will give you a fully charge voltage at 16.8V, which will far exceed the Absolute Max Instantaneous voltage by quite a large margin.

 

[xpitxbullx]

Re: Interest for MiniHID Li-Ion rechargeable solut

Ted Bear was completely aware that it was the B10N008 ballast. I told him that 4xR123 would be 16.8V. He said that with the voltage drop under load it would fall in the safe 16V range.

I tried to see if perhap he was mistaken about what I was talking about but he knew exactly what I was saying and said it was safe.

Still scared to try it. Who's up for the test?

 

[Burnt_Retinas]

Re: Interest for MiniHID Li-Ion rechargeable solut

xpitxbull,

Not me. I share Greg's caution here. I believe the first batch of UFO's MiniHids used a different ballast to this one and maybe someone along the line has confused the two?. This batch used the 10.2V versions. It may be possible Ted Bear was given wrong info but as Ted Bear has a lot of experience with HID's I can only conclude he was either given misleading information of someone's results/configuration or he hammers his lights to the max if he's done it himself to a B10N008A. The giveaway something is amiss is your comment "He said that with the voltage drop under load it would fall in the safe 16V range". The B10N008A has no mention of voltages anywhere near this "safe 16V range". At least not in the documentation I have read. In fact none of the ballasts mention 16V being safe. It's up to you though and I'd be curious if you could point me to the specification sheet that suggests 16V is safe.

Regardless of either being the case, I personally will not want to exceed manufacturers absolute maximum specs for mine. You can do as you wish.

jdriller,

You were already on the list. Yes I can set it to 12V. Want 13V instead so you can get close to matching the B10N008A ballast's in the Mini? I haven't tested it on a 12V ballast at 13, but both the power supply and 12V ballast should be ok. You specify the voltage next to where you are on the list when you decide what voltage you want based on which ballast you have.

Chris

Re: Interest for MiniHID Li-Ion rechargeable solut

I understand. I was just pointing out the conversation we had. I'm well aware of the spec sheet and the data it shows. Pesonally, I'll stick to the specs or close to it. I'm not risking such a unique flashlight to 16V...

...but it is tempting. /ubbthreads/images/graemlins/evilgrin07.gif

Re: Interest for MiniHID Li-Ion rechargeable solut

Just for the record, I still want my regulators set to 11.38V.

Please add me to the 11.38v list (assuming it's the best brightness/runtime compromise)

Re: Interest for MiniHID Li-Ion rechargeable solut

To mine, safety is more important. Although I can get the spare bulb somewhere at ~$60 but it is still not cheap.
Stick to the Spec. of WA, I would like mine set to 11.0v.
Thanks alot, chris~
